There are different types of the fluid that a woman will discharge:
1. There are the natural discharges which come out normally and cannot be controlled by the woman. These do not come about as a result of any sexual desire or stimulation. These liquids are pure and do not invalidate wudû’, according to the strongest opinion of the scholars.
These fluids are comparable to mucus, saliva, and phlegm. These fluids come out from the womb or the vagina, so they cannot be compared to urine. All women experience these fluids on a regular basis, and had they warranted a special ruling with respect to purification and prayer, then Allah would most definitely have revealed this ruling to our Prophet (peace be upon him). Allah says: “And your Lord is not forgetful.” [Sûrah Maryam: 64]
2. Then there are fluids that are discharged from the woman’s vaginal area during sexual arousal, either when she is with her husband or on account of her thinking sexual thoughts. These fluids have the same ruling as a man’s pre-semenal fluid (madhî). These invalidate wudû’ in order for the woman to attain a state of ritual purity. They are mildly impure substances, meaning that they can be cleaned off by merely splashing water on the affected area.
3. Then there is the fluid that a woman discharges upon reaching orgasm. It is a smooth, yellow liquid that occurs upon reaching sexual climax either through sexual intercourse or when thinking about sex. After releasing it, the woman will feel weak. This fluid is governed by the same rulings that apply to semen. It is a pure substance. However, the woman will have to perform a full bath (ghusl) after discharging it in order for her to attain a state of ritual purity.
The Prophet (peace be upon him) was asked: “Does a woman have to bathe if she has a wet dream.”
He said: “Yes, if she sees the fluid.” [Sahîh al-Bukhârî (282) and Sahîh Muslim (313)]
And Allah knows best.
